Had an Alfa in for a clutch today. When finnished the car wouldn't start and had the key light on and injection light on.

This didn't have 16 pin but the small connector plug on O/S inner wing.
Went in with Snap on heratige scanner and got key not programmed fault .

Looking at live data ECU voltage was at 0.1v.
Turned out to be the wiring corroded to 3 relays & 2 fuses attatched to the front of the battery tray. I guess in moving them out of the way we had managed to disturb the rotten wiring.
